​Last week, the government were caught out. After years of denying that the NHS would be threatned by TTIP, new legal advice showed otherwise.

The story exploded. It was in newspapers, online and all over social media. Every politician in the country saw it. And now, other campaign groups are coming on board.

38 Degrees, one of the biggest campaign groups in the UK, are now working on this too. Together their members have sent tens of thousands of letters to MPs demanding action to save the NHS from TTIP. You can join in here.

Taking part in the 38 Degrees action matters. It will show the government how many people worry about this, wherever they live and however they vote.

And imagine how it would look from the goverment's perspecitive. First, People's NHS waded in and made this is an issue. Then it was in the newspapers and online. Now one of the biggest groups in the country is taking up arms.
